Abstract
The utility model discloses a four-path high-temperature power supply pipe nipple of a high-temperature slim hole. The pipe nipple comprises a shell and four paths of power supply pipe nipple circuits arranged inside the shell. The four paths of power supply pipe nipple circuits are connected with pins of the shell and respectively integrated with rectification filter circuits, and no external circuit is needed. The four-path high-temperature power supply pipe nipple is characterized by being convenient in utilization and compact in structure.
Description
Technical field
The utility model relates to integrated circuit fields, relates in particular to a kind of high temperature slim-hole four road high temperature power supply pipe nipples.
Background technology
The existing mode that High Level AC Voltage is converted to stable low-voltage DC mainly contains switching power supply regulator and linear power supply pressurizer.Switching power supply regulator the single-chip form arranged with modular form, it is little that the pressurizer of single-chip has a volume, conversion efficiency is high, cost is low, use easily characteristics, disturb large (tens to millivolts up to a hundred) but its shortcoming is ripple, it is poor that the output current ability is compared the module pressurizer, and maximum operation (service) temperature can only arrive 150 ℃.It is high that modular switching power supply regulator has conversion efficiency, and output current is large, and serviceability temperature is high, can arrive 175 ℃, disturbs large (tens to millivolts up to a hundred) but its shortcoming is ripple.Present linear power supply has ripple and disturbs little characteristics mainly take single chip solution as main, but because conversion efficiency is low than Switching Power Supply, so output current ability, also need external current rectifying and wave filtering circuit during use, increased the trouble of using, the upper limit of its serviceability temperature is 125 ℃.
The utility model content
The purpose of this utility model provides a kind of high temperature slim-hole four road high temperature power supply pipe nipples, is integrated with current rectifying and wave filtering circuit, easy to use, compact conformation.
The utility model adopts following technical proposals: a kind of high temperature slim-hole four road high temperature power supply pipe nipples, comprise shell and setting four-way power supply pipe nipple circuit in the enclosure, four-way power supply pipe nipple circuit is connected with the shell pin, it is characterized in that: be integrated with respectively current rectifying and wave filtering circuit in the described four-way power supply pipe nipple circuit.
Be provided with copper radiator on described four-way power supply pipe nipple circuit and the current rectifying and wave filtering circuit, copper radiator and shell are connected by screw.
Described pin adopts high-temperature hook-up wire.
Described shell is stainless steel casing.
The utility model is on the basis of existing linear power supply, and integrated rectifying and wave-filtering wave circuit does not need external circuits, has the characteristics such as easy to use, compact conformation; Added simultaneously radiator, be connected as a single entity with shell, radiating effect is better, guaranteed that power supply has the output of larger electric current, can be operated in 175 ℃ the hot environment, the alternating current of transformer output is converted to the galvanic current pressure, and output dc voltage has the ripple less than 1mV, reliable operation.
